Explanation of the data set

We use a dataset from Kaggle to study obesity over time.

According to the WHO, a person is overweight when his or her body mass index (BMI) is above 25 and obese when it is above 30. The problem has reached epidemic proportions as of 2017, more than 4 million people were dying each year from overweight or obesity, according to a Global Burden of Disease study.





The dataset has 6 variables:

  • country
  • the year
  • BMI
  • the confidence interval
  • gender

Here is an extract from our obesity dataset:

Country Year Sex Obesity Std_Dvt
Afghanistan 1975 Both sexes 0.5 [0.2-1.1]
Afghanistan 1975 Male 0.2 [0.0-0.6]
Afghanistan 1975 Female 0.8 [0.2-2.0]
Afghanistan 1976 Both sexes 0.5 [0.2-1.1]
Afghanistan 1976 Male 0.2 [0.0-0.7]

In order to be able to make maps we also imported the World dataset from R. This dataset allows us to have the names of the countries in ISO3 format and to obtain various information about the countries, such as the number of inhabitants. Here is an extract of the dataset:
